Near-Earth Objects (NEOs), like species extinction events, present a great threat to our home planet and human kind. The motivation of designing this architectural framework is the current lack of structured architecture for the process of detecting, characterizing and mitigating these NEO threats. Due to the recent establishment of the NASA's Planetary Defense Coordination Office (PDCO), it is critical...
One of the future trends in UK distribution network development is to increase distributed generation (DG) penetration. In this paper, the suitability of using power electronic controller to address issues caused by increasing DG penetration is analyzed from three aspects: voltage regulation, fault current restriction and network loss reduction. The back-to-back voltage source converter (B2B-VSC)...
One key factor that ensures smooth data delivery over the Internet and keeps the Internet healthy is the well-being of the Internet’s inter-domain routing. In today’s Internet, the de facto standard inter-domain routing protocol is the Border Gateway Protocol, or BGP, that keeps every BGP router updated about which BGP router is the next hop in reaching a particular network and which autonomous systems...
Considering data size and privacy concerns in a distributed setting, it is neither desirable nor feasible to translate data from one resource to another in data mining. Rather, it makes more sense to first mine knowledge from one data resource and then translate the discovered knowledge (models) to another for knowledge reuse. Although there have been successful research efforts in knowledge transfer,...
In this paper, a semi-analytical method is proposed to accurately and efficiently calculate the impedance of grid-type power distribution network (PDN) on interposer. An equivalent plane PDN is constructed to obtain the same impedance curve as that of grid-type PDN. Furthermore, a modified resonant cavity mode is applied for the equivalent plane PDN to eliminate the deviation between the equivalent...
In a contemporary Chinese full time college education, it is an emerging need to know how to evaluate the quality and effectiveness of the network-based courses which have played a more and more important role in assisting classroom instruction. In this study, an evaluation framework for assessing network assisted courses is proposed based on the particular functions of the THEOL learning management...
Financial forecasting is the basis for budgeting activities and estimating future financing needs. Applying machine learning and data mining models to financial forecasting is both effective and efficient. Among different kinds of machine learning models, kernel methods are well accepted since they are more robust and accurate than traditional models, such as neural networks. However, learning from...
H. pylori in the oral cavity may be the possible underlying cause of recurrent stomach illness. Therefore, we test the H. pylori in the oral cavity through chromaticity analysis and try to find an easy and convenient H. pylori detection way, which is of clinical necessity. Integrate the results of chromaticity to establish the intensity of redness as value. The average ratio of the red chromaticity...
With the reformation of project investment and finance system, multi-regional investment project, which is of great investment, long construction cycle, complex influence factors and so on, needs distribution investment among benefited regions. In view of investment-distribution decision problems, this paper introduces some concepts such as optimal expectation level, tolerating limitation, relative...
From the operation mechanism of the ball mill with double inlets and outlets, this paper gives a research work to the simulation of the ball mill with double inlets and outlets, and proposes a corresponding mathematical model of the six controlled with six control variables of the ball mill with double inlets and outlets, and simulates with Matlab using the operation data of a power plant. The result...
In this paper, a modified virtual feedforward control (VFC), is presented for asymptotic disturbance rejection. The proposed VFC control is able to reject the periodic disturbances efficiently in nonminimum phase processes, and has been extended from SISO application to MIMO cases. The robustness of this control scheme is analyzed. The effectiveness is sustained by simulation.
